Unity CEO John Riccitiello came to TechCrunch Disrupt SF to give everyone an update on the world’s most popular game engine. You might not be aware that most of the games you’re playing, especially mobile games, are built using Unity.
For those not familiar with game engines, Riccitiello started by describing game engines very clearly. Back in the days, “[game developers] would write out a game program that had lots of art assets, lots of animation, lots of sounds. But they also had to write a rendering engine, to write a system for animations, to write a system for sound, to write a system for physics,” he said.

And when you wanted to port your game to another platform, you basically had to start over. Unity works on 30 platforms, including Windows, iOS, Android, Nintendo Switch, Playstation 4, Oculus Rift, etc. Unity competes with Epic’s Unreal Engine, the game engine behind Fortnite and many games on the PS4 and Xbox One.
There are also less popular game engines from Valve, Amazon and others. The biggest game developers behind AAA franchises (think Battlefield or Assassin’s Creed) have their own in-house engines.
But it’s clear that Unity has captured a huge chunk of the market. According to Riccitiello, every month, people download 2 billion copies of Unity games. People tried at least one Unity game on over 3 billion devices.
In the past, Unity said that half of mobile games run on Unity. But it turns out Unity now also powers a lot of games on gaming consoles and computers.
“It’s pretty much half of all games period. We have different market shares, depending on the platform. But more than half of all mobile games built for there are built in Unity. More than 60 to 70 percent — depending on the platform — of everything built for machines for virtual reality or augmented reality or any of the XR platforms are built in Unity,” Riccitiello told interviewer Lucas Matney. “And then, about a little over half of all the games built for Nintendo’s platforms are built in Unity, a little bit less than that for Xbox and Sony. But in aggregate it’s more than half.”
One of the reasons why Unity became so successful is that its pricing structure is developer-friendly. Game companies don’t have to give a cut of their revenue to Unity, they pay Unity per seat on a subscription basis. Other companies sometimes ask you to sign a revenue-sharing deal to use their engine.
Even more important than numbers, Riccitiello thinks that Unity is all about enabling creators by giving them the right tools.
“What powers Unity is a simple philosophy, which is the world is a better place with more creators,” he said. “We drive ourselves to put the most powerful tools possible in the hands of creators, small and large so they can realize their dreams.”
